Add the GLIB_AVAILABLE_IN_ALL annotation to all old functions (that haven't already been annotated with the GLIB_AVAILABLE_IN_* macros or a deprecation macro). If we discover in the future that we cannot use only one macro on Windows, it will be an easy sed patch to fix that. https://bugzilla.gnome.org/show_bug.cgi?id=688681
